BoilerFaultCodesYour heat pump's internal control computer has detected an electrical fault with the unit that powers the motor, preventing it from running.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: Inverter Error
What causes this fault?
This fault occurs when the internal power management system fails to supply the correct electricity to the compressor motor. It is usually triggered by a short circuit or a failed component on the inverter circuit board that prevents the heat pump from physically starting its heating cycle.
This fault can be more frequent during periods of high demand in winter, as the inverter has to work harder and generate more heat to maintain high flow temperatures.
Engineer required
This fault requires a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
